MARTIN G. HIGGINS, OF .IPITTSBURGH, PENNSYLVANIA, ASSIGNOR T0 PITTSBURGHGAGE & SUPPLY COMPANY, OF PITTSBURGH, PENNSYLVANIA, A CORPORATION OFPENNSYLVANIA.

GAS BURNER FOR IRONING MACHINES.

To all whom it may concern.

Be it known that I, MARTIN Gr. Hreorns, a citizen of the United States,and a resident of Pittsburgh, in the county of Allegheny and State 01''Pennsylvania, have invented a new and useful Improvement in Gas Burnersfor Ironing Machines, of which the followinnis a specification.

The invention relates to ironing machines, particularly those adaptedfor domestic use and which comprise a gasdieated ironing shoe and arotatable padded roll adjacent to the shoe.

The object of the invention is to provide such ironing machines with animproved gas burner so that the shoe may be uniformly heated from end toend, and also to provide an improved burner which may be readilysubstituted in place of the burners now in use in ironing machines.

The invention is illustrated in the acconipanying sheet of drawings ofwhich Fig. 1 is a rear elevation of the upper portion of an ironingmachine, part of the outer casing or hood of the shoe being broken awayto show the burner; Fig. 2 a horizontal central. sectional view throughthe burner; and Fig. 3, a vertical sectional view to enlarged scaletaken on the line TIL-III, Figv l.

The ironing machine shown herein is typical of the general constructionand arrangement ot a number of machines now on the market. It comprisesa frame 1 which supports a padded roll 2 and an ironing shoe 3, the rollbeing adapted to be rotated by means of a motor, not shown, and the shoebeing adapted to be heated by a gas burner arranged adjacent to theironing wall of the shoe. The shoe is provided with end portions 7 and 7and with a cover 8, and the frame also supports a feeding table l and areceiving table Articles to be ironed. are fed upon the roll 2 from thetable l and are moved by the roll into contact with the shoe. Afterpassing between the roll and shoe the articles drop upon the receivingtable 5, either completely ironed or in a convenient position to bereadily passed again between the roll and the shoe.

To uniformly heat the shoe from end to end, there is provided a burnerpipe having a gas inlet at one end and gas outlets adjacent to the shoe.The pipe is closed at a point adjacent to its inlet end and a bypassconduit extends from a point between the gas inlet and the closedportion of the pipe to substantially the center of the burner portion ofthe pipe so that the supply of gas may flow equally in both directionsfrom the center of such burner portion towards its ends.

The burner pipe may be an ordinary gas pipe (3 supported at its ends bythe end portions 7 and 7 of the shoe 3. The outer end of the pipe 6 maybe provided with a valvecontrolled or other type of inlet 17, wherebyconnection may be made to a con duit 9 leading; from asource of gassupply. Preferably, the closing of the outer end of the pipe 6 isellected as indicated by a plug 10 at a point close to and 'nside of theend 7 of the shoe. The bypass conduit may also be gas pipe 11 closed atits ends and provided adjacent to such ends with lateral openings 1% and13. These openings register, respectively, with openings 1% and 15formed in the pipe 6, the openings 15 being substantially at the centerof the burner portion of the pipe. A. convenient and etitective way ofattaching: the lay-pass conduit Ill to the pipe 6 is by forming a weldconnection as indicated at 16 in Fig. 3.

By providing the ironing machine with a burner such as shown herein andjust ex plained, gas for heating the ironing shoe flows through theby-pass conduit 11 to the center of the pipe 6 and then flows outwardlytowards each end of the burner por tion of such pipe, with the resultthat the shoe becomes uniformly heated. By arrang ing the by-passconduit entirely within the ends '7 and 7 of the shoe, as well as withinthe cover 8, ironing machines which are in use and which have the usualform. of single pipe burners may be provided. with the improved lnirnerwithout altering the openings in the hood, and without providingadditional openings. To substitute the new for an old type or burner, itis only necessary to remove the hood 8 from the ironing shoe, and thento slip the new burner into openings of the shoe ends 7 and; 7 used forattaching the old type of burner.

Accord ng to the provisions of the patent statutes, I have described theprinciple ant operation of my invention together with the constructionwhich I now con. to represent the best embodiment thereof. However,

I desire to have it understood that, within the scope of the appendedclaims, the invention may be practiced by other forms of con structionthan that particularly illustrated and described herein.

1 claim:

1. A. gas burner for heating the shoe of a domestic ironing machinecomprising a pipe closed at one end and having a gas inlet at its otherend, and lateral gas inlets intermediate of its ends, said pipe beingclosed near its inlet end, and a lay-pass conduit extending "from saidpipe at a point bet-ween its inlet and closed portion to substantiallythe center of the burner portion of the pipe.

2. A gas burner for heating the shoe of a domestic ironing machinecomprising a, pipe closed at one end and having a gas inlet at its otherend, a plug in said pipe adjacent to its inlet end, and a lay-passconduit extending from said pipe at a point between its inlet and saidplug to substantially the center of the burner portion of the pipe.

In testimony whereof, I have hereunto set my hand.
